Graham's solution is excellent. You could also have a couple of buttons between the two lists, with arrows (one right, one left) to move items to and remove them from, the sub-group list. And an additional pair to the right of the sub-group list (one up, one down) allowing reordering. This would allow a completely "control" (e.g. Buttons and lists) way of doing it.
Finally, you could present the sub-group info above or below the sub-group list. > From: Graham Cox <graham....@bigpond.com> > Date: Thu, 15 Oct 2009 17:45:59 +1100 > To: Peter Hudson <peter.hud...@mac.com> > Cc: <cocoa-dev@lists.apple.com> > Subject: Re: SelectedRowIndexes > > > On 15/10/2009, at 5:24 PM, Peter Hudson wrote: > >> The user has an NSTableView in which is presented a number of >> elements ( 1 per row, typically 20 - 200 rows ) out of which they >> need to produce a number of sequenced sub groups. >> The user presses the 'Start Sub Group' key ( i.e. clear the sequence >> selection cache ) and then by picking a possible sequence ( one row/ >> element at a time ) they build a group. >> As the group is selected, further info about that particular sub >> group of elements is presented. >> They can close/abort/store a given sub group at any time. > > > That does make some sense, but falls into the trap of not avoiding > modes (in this case a "build subgroup" mode). > > If it were me, I'd have two lists: a master list and a sub-group list. > Drag items from the master to the group, and allow drag reordering of > the group to set the sequence.
